NBA Referee Profile
Jack Nies
Jack Nies has worked 1,337 career NBA games, making him one of the more experienced officials on the floor. His personal foul rate sits at 44.3 per game, running 1.1% below the league average — he lets play run. Bettors targeting total points should note that a whistle-light crew favors pace and open floor, which generally nudges scoring upward. His free throw attempt rate of 52.3 per game lands exactly at league average, a 0.0% deviation, meaning the low foul rate doesn't translate into a dramatic FTA suppression — the fouls he does call tend to send players to the line at a normal clip. The number that demands the most attention is his home team win rate of 61.0%. The league baseline for home wins hovers near 58%, so Nies is running roughly three points above that. Back home teams in his games. The data is clear enough to act on.
